Description
Electrical thermometer model Tx293
These model Tx293 electrical thermometers are used for the measurement of exhaust gas temperatures on diesel engines and turbines. The standard temperature range is 0 ... 850 °C for thermocouples, 0 ... 600 °C for resistance thermometers. The thermowells are designed for the loads which occur in medium and large power plants. These thermometers are suitable for ambient temperatures to 200 °C. The process connection is made via male connectors, with a standard insertion length of 202 mm.

Resistance thermometer for model TR293
Neck
■■ Class B
Sensor tolerance value per DIN EN 60751
Material Stainless steel 1.4571
The combination of a 2-wire connection with Class B is not permissible, because the lead resistance of the measuring insert overrides the higher sensor accuracy.
Neck length MH 50, 100 mm others on request
For detailed specifications for Pt100 sensors, see Technical Information IN 00.17 at www.wika.com.
Diameter 15 mm
Thermocouple for model TC293 Sensor type ■■ K (NiCr-Ni) Application range up to 850 °C ■■ J (Fe-CuNi) Application range up to 600 °C Listed thermocouples are available both as single or dual thermocouples. The thermocouple will be delivered with an insulated measuring point. Tolerance value For the tolerance value of thermocouples, a cold junction temperature of 0 °C has been taken as the basis.
